<p>Is there a way I can have rustup-toolchain-install-master install things for the "wrong" platform? Right now, rustup thinks that the Apple DTK is x86_64 (because it kinda is), but I'd like to be able to install a ci build for aarch64.</p>

<p>it sometimes gets confused for me and starts treating --host or whatever as commits, though, so you might need to mess with it a bit</p>

<p>Related question: Can I cheat and install a component from a try build into the wrong toolchain?</p>
<p>I'd like to try cross-compiling from x86_64 darwin to aarch64 darwin using these artifacts. Do I need to configure the try build to build <em>both</em> platforms?</p>

<p>Right now, I've only try-built the aarch64 version.</p>
